Hi Wendy,

Thanks for sending the song file. I figured out how to fix it, but I'm not sure how this happened.

When I first opened your song and clicked on the Plugins tab of the mixer, the Piano track said it had Sforzando on it, which is a synth and only for MIDI tracks, though it was an audio track with a RealTrack on it. So though the track name had turned green, it was still kind of a MIDI track, but trying to play audio, so was silent.

I tried to replicate this issue with a new song and wasn't able to (yet), but I did figure out how to fix yours. I clicked on the track, went to Select MIDI SuperTrack for this Track, picked a random one, clicked OK. Then I went to Select MIDI SuperTrack again, and chose "No MIDI SuperTrack" to remove it.

Now it's a normal MIDI track, without Sforzando, and I could switch to a RealTrack with no issues.

Was this song created with the 2018 version of BIAB, or is it an older song created with a previous version?

Thanks
Kent
